Removes HTML tags from feed titles

As per: codeforamerica/citygram#247

Thank you! I'm not sure this will give properly linked urls in each scenario: when viewing the citygram map, in the email, and when viewing the email in the browser.

Can you confirm that this will lead to properly linked items in each scenario? I'm a bit suspicious that maybe not, as there are no a tags, so nothing related to linking to strip out.

hmm, good question. I'll check. The main citygram app 'hyperlinks' plain text, so I think...as long as this text is plain text and has a properly formatted URL it should be okay.

Okay! Spent a little time over the weekend on this. You're totally right, this is much more complicated...

• Was able to setup citygram to pull from my locally hosted version of this PR - yay!
• The citygram app has two hyperlink() methods - one in javascript (Autolinker.js) and one in ruby (erb I...think). The JS version works great if you have text with a link in it: it will find a link in the text, and wrap an <a> tag around it. The ruby version does not: it just wraps a link around the full text, which sometimes renders badly.
• I looked through the other publishers and it look like san diego is the only publisher with a link in the published text.
• I saw a couple another thread you opened, and some suggested improvements options: Pass raw event values to front-end css codeforamerica/citygram#244 -- I think this issue will require some change to the geojson format that is published to truly fix it. I'll make comments over on that thread...seems like support needs to be in citygram before its worth finalizing this PR.
